xchat-greek is a Perl script to allow reading both 8-bit ISO and UTF-8 text inside xchat. It is intended for Greek IRC users. It can be easily modified to support more ISO codepages (tested with Baltic, Cyrillic and Turkish; probably also works with Arabic and Hebrew).

The klish is a framework for implementing Cisco-like command-line interfaces on Unix systems. It is configurable through XML files. "Klish" stands for "Kommand Line Interface SHell". The klish is a fork of clish-0.7.3. The original clish was developed by Graeme McKerrell. The klish adds some new features, but is compatible (as much as possible) with clish's XML configuration files.

ULS is an library for general purpose lexical analysis, with support for UTF-8. It comes with C/C++ libraries and a couple of tools for Linux and Windows. It's a intuitive, practical, flexible, and optimized tokenizer. ULS can instantiate multiple objects for lexical analyses. The objects can process multiple (nested) inputs of different languages. The language specification is specified in configuration file suffixed by *.ulc. ULS can tokenize the input file, which encoded by UTF-8. The input files may contain the words in a localized language as identifiers. ULS can stream the tokens from many input files to another output (files).The stream can be stored in a *.uls file and replayed from it whenever necessary.

utfout is a command-line tool that can produce UTF-8 (Unicode) strings in various ways and direct them to standard output, standard error, or direct to the terminal without the need for shell support. Strings can be repeated, delayed, randomly-generated, written to arbitrary file descriptors, interspersed with other characters, and generated using ranges. printf(1)-style escape sequences are supported along with extended escape sequences. utfout(1) sits somewhere between echo(1) and printf(1).
